Question 1 of 120
Exam 300-630: Question 1 - Image 1
Refer to the exhibit. How is the ARP request from VM1 forwarded when VM2 is not learned in the Cisco ACI fabric?
Suggested Answer: A

When VM2 is not learned in the Cisco ACI fabric, Leaf 101 forwards the ARP request to one of the proxy VTEP spines. This is because the local leaf (Leaf 101 in this case) does not have information about VM2 and since ARP flooding is disabled, it encapsulates the ARP request toward one of the Proxy Anycast VTEP addresses available on the local spine nodes to avoid flooding along the local multi-destination tree.

Question 4 of 120
Which two actions are the Cisco best practices to configure NIC teaming load balancing for Cisco UCS B-Series blades that are connected to the Cisco ACI leaf switches? (Choose two.)
Suggested Answer: B, D

To configure NIC teaming load balancing for Cisco UCS B-Series blades connected to the Cisco ACI leaf switches, it is recommended to use LACP in active mode because it provides dynamic link aggregation and can automatically configure and manage the aggregation. Additionally, creating a vPC (Virtual Port Channel) allows link redundancy and load balancing across multiple physical links while simplifying the network topology. vPC also provides benefits such as loop prevention and increased bandwidth without needing additional protocols.

Question 5 of 120
Exam 300-630: Question 5 - Image 1
An organization migrates its virtualized servers from a legacy environment to Cisco ACI. VM1 is incorrectly attached to PortGroup IT|3TierApp|Web. Which action limits IP address learning in BD1?
Suggested Answer: A

To limit IP address learning in BD1, the appropriate action is to enable Enforce Subnet Check. This feature ensures that only IP addresses within the subnets defined in the bridge domain are learned and allowed. In this case, enabling this feature will restrict IP address learning to the 172.16.0.0/24 subnet, which should prevent the incorrect IP address (192.168.0.10) from being learned and associated with BD1.
